In this paper we present the design of a Linux application level secure web switch, called LSWS, which is based on OpenSSL package. It is intended to be used a front end switch for a secure web server cluster. It allows flexible specification and dynamic update of content switch rules. Two versions of LSWS were implemented. One based on dynamic forking of child processes and other based on prefork idea similar to Apache. The overheads of content switching and SSL processing are analyzed using WebBench. We also compare its performance with Intel 7280 XML director.
